PHONOGRAPH-OPERATING- MECHANISM.

Application filed August 30, 1918.

T 0 all whom it may concern:

Be it known that I, ARTHUR H. FRANKIE, a citizen of the United States, and resident of Manitowoc. in the county of Manitowoc and State of ll isconsin, have invented certain new and useful Improvements in Phonograph-Operating Mechanism; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to new and useful improvements in means for automatically controlling the playing operation of a phonograph, more particularly of the disk type. It is primarily the object of my invention to provide an improved mechanism whereby the phonograph is caused to indefinitely repeat the playing of a record thereon, or whereby the playing rotation of the turntable may be stopped upon completion of a single playing of the record.

One important object resides in the provision of mechanism of the foregoing character which is readily adjustable for individual records, both with respect to the general size of the record, and with respect to the length of playing groove for such general size of record, whereby the sound box needle may be caused to accurately engage the starting portion of the record groove in repeating the playing of the record, and whereby the playing operation will be accurately stopped at the end of the record groove.

A further object in this connection resides in the provision of a mechanism which ma y be most readily controlled to selectively perform either of these operations.

A still further and important object resides in the provision of an actuating mechanism operable as an automatic stop, wherein incidental to the automatic stop action, the sound box is lifted from the record and the tone arm shifted to starting position to permit removal of the record without manual manipulation of the tone arm or sound box.

Another object in this connection resides in the provision of means for automatically engaging the sound box properly in the sound groove upon starting playing of the record. 7

A still further object resides in the pro vision of a mechanism including the above mentioned features, wherein the power for operation of the mechanism is procured from driving rotation of the turn-table Specification of Letters Patent.

spindle to thus eliminate the provision of independent operating means for the mechanism'.

A still further object resides in the provision of such a mechanism wherein shifting movements of the various paits are carried out in a positive and even manner so as to insure an efficient operation with a maximum simplicity and lightness of structure, and so as to prevent the possibility of dam age to either the record or needle in the various relative movements thereof incidental to operation of the mechanism.

With the above and other objects and advantages in view, my invention resides more particular y in the novel construction, combination and arrangement of parts which will be hereinafter described and pointed out in the appended claims.

' Fig. 9 is a detailed sectional view showing the clutch drive connecti for the turn table spindle.

Referring now more particularly to the accompanying drawings, 10 designates an ordinary turn-table spindle of a phonograph and 11 designates a fragmentary portion of the turn-table, over which is horizontally movable a pivoted tone-arm 12 having one end mounted in the usual vertical bearing sleeve 13, and having its other end enlarged to form a transverse sleeve 14 in which is rotatably mounted one end of the goose-neck shank 15 of-the sound box 16. The present embodiment of my improved operating mechanism comprises a base plate 17 which carries the various parts of the device, the major portion of thi base-plate being disposed under the turn-table and being secured to the playing base of the phonograph structure by suitable screws 18.

To impart movement to the tone-arm and to the sound box shank by the power of the turn-table spindle 10, at predetermined times hereafter to be discussed in detail, a collar 19 is rotatably mounted on the spindle and is provided with a transverse slot there in, in which is disposed a toothed end portion of an intermediately pivoted pawl lever 20, said toothed end portion of the lever being resiliently urged to engagement in locking notches 21 of the spindle, whereby to procure rotation of the collar 19 with the spindle. This collar carries a gear wheel 22 which meshes with a gear wheel 23 journaled on the base plate 17 and having connected therewith a pinion 24 meshing with peripheral gear teeth on a relatively large cam d1sk 25 also ournaled on the base plate,

this gearing extending in a general direction toward the tone arm pivot sleeve 13. Piv oted eccentrically on the cam disk 25 adjacent its center, and spaced thereabove by the pivot stud 26 is a pitman link 27 which projects from the periphery of the turn-table, and carries at its outer end a swivel. post 28.

A casing 29- is secured on the base plate 17 between the tone arm pivot 13 and the turn-table and journaled in this casing is a vertical shaft 30, the upperend of which ex tends through the top of the casing, and has a collar 31 adjustablysecured thereon by the set screw 32, this collar carrying a crank arm 33 having a roller 34 at its outer end engagcable with the slide of the tone-arm to swing it horizontally upon rotation of the .shaft. Journaled horizontally in the casing is a shaft 35, one end of which projects from the casing and carries an offset crank arm 36. Fixed on the shaft within the casing is a lever 37 which extends below the shaft for securement to its lower end of one end of a retractile spring 38 having its other end anchored to the casing. The upper portion of the lever is longitudinally slotted, and passed therethroughis an arm 39, one end of which is secured to a collar 40 loose on the shaft 30. This arm extends outwardly of the casing through a horizontal slot in the side portion thereof adjacent the pitman link 27, and the outer end of the arm is slidably passed through the upper end of the post 28 swiveled on the outer end of the pitman link. Extending from the upper portion of the shaft 30 within the casing is a crank arm 42 having pivoted thereto one end of a link 43 which has its other end bifurcated to loosely receive the upper reduced end of the lever 37, the crank arm 42 extend ing toward the pitman link side of the easing obliquely with respect to the arm 39, whereby the arm and its link 43 are angularly disposed with respect to each other. The shaft 30 is resiliently urged to rotate in a counter-clockwise direction (Fig. 1) by a spring 44 coiled on the lower portion of the shaft and having its ends secured respectively to the casing and to a collar 45 fixed on the shaft immediately below the collar medium of the lever 37, it being noted'that one complete rotation of the cam disk 25 carrying the pitman link will oscillate the arm 39 to procure a complete cycle of-movement of the various parts described.

To lift the sound box by rocking movement of the crank arm '36, a bracket plate 46 is secured to the intermediate end portion of the tone arm, carrying a depending bracket arm to which is intermediately pivoted a lever 47 having a bearing head 43 on its rear end disposed over and slidably engageable by the crank arm 36. The forward end of the lever has'a slotted pivotal connection with one end of a lever arm 49, which has its other end enlarged in ring shape to engage on the reduced inner por tion of the head of a retaining bolt 50 which is threaded in the end of that portion of the sound box shank which is disposed in the bearing collar of the tonearm, said bolt, which is of an exceedingly flat type, serving together with the enlargement of the crank arm 49, to hold the tone-arm shank in place, the crank arm 49 being rotatable on the bolt. To procure rotation of the journaled portion of the goose-neck shank of the sound box, and consequently procure lifting move ment of the sound box upon rotation of the crank arm 49 in a clockwise direction, in a manner permitting lifting of the sound box for replacing neeindependent manualdies or for any other purpose, a leaf spring 51 is mounted in a groove extending transversely in the outer face of the bolt head, this leaf spring being secured to the bolt head at one end andhaving a beveled tooth 52 on its other end urged by the spring for engagement in a recess 53 in the ring enlargement of the crank arm, the bevel of the tooth beingdisposed at the upper side thereof, in the arrangement shown in Fig. 2 of the drawings, whereby it is cammed out of the recess in clockwise independent movement of the journaled sound box shank, but locked in the recess upon clockwise movement of the crank arm.

Tracing now the operation of the structure heretofore described, it is seen that a half-rotation of the cam disk from set position shown in Fig. 1 will swing the arm 39 in a counter-clockwise direction to rock the lever 37 and the shaft and lift its crank arm 36 to rock the lever 47, swinging the lever arm 4L9 downwardly and consequently lifting the sound box. 16 from the grooves of the record. The rocking movement of the lever 37 permits rocking movement of the shaft 30 under the influence of its spring 44, and as the needle of the sound box leaves the groove of the record, the crank arm 33 will swing to engage the tonearm and rock the tonearm back to starting position. The lifting movement of the sound box is thus effected positively through the gear train connected with the turn-table spindle 10, while the swinging movement of the tone-arm is effected by the spring 44 which is comparatively light, it being noted that the tone-arm moves very readily on its pivot. Upon a second half revolution of the cam disk 25 to return the mechanism to set position, the crank arm 33 swings away from the tone-arm, which is left in proper starting position, and the sound box is gradually lowered onto the record to engage its needle in the grooves thereof. To stop the outward swinging movement of the tonearm at proper positions for engaging the sound box needle in the starting portions of the grooves of different sizes of records, a bar 5% is mounted for'sliding movement transversely under the tone-arm in a hearing plate secured on the base plate 17, the inner end of this bar being extended laterally to form a shoe engagea-hle by a pin 56 depending from the bracket plate 416 of the tone-arm, this pin incidentally also serving to actuate the mechanism at the termination of a plaving operation of the record. The bar is herd against sliding movement by a leaf spring 5T secured to the bearing plate and frictionally engaging one edge of the bar, the spring 57 being stronger than the spring 44: which turns the crank arm, although it will be appreciated that a more positive holding means for the bar may be provided. Thus, the bar 544 may be shifted so that the pin 56 will engage its inner end to stop the setting movement of the tone-arm in accordance with the size of record which is disposed on the turn-table, and with the movement of the tone-arm thus halted, lifting movement of the sound box may continue to the full limit defined by the movement of the pitman link 27, the rock lever 37 sliding in the slot of the link L3 during such continued movement and in the resetting movement of parts, the crank arm remains idly pressing its roller against the tone-arm until the upper end of the lever 37 has moved back to the end of the fur-cations of the link 43, at which time the resetting movement of the crank arm will be taken up.

To automatically control the actuation of the mechanism heretofore described at the expiration of playing operation of a record, to either repeat said playing operation or to entirely stop the playing action, a lever plate 58 is pivoted at 58 on the base plate 17 under the turn-table, and this lever plate 58 is provided in its outer portion with a lateral arm 59 which has its free end curved toward the depending peripheral brake wall of the turn-table, a friction block 60 engageable with said wall being carried on the end of the arm. Extending outward from the intermediate portion of the arm is a fingerpiece 61 projecting from the periphery of the turntable, and the lever plate adjacent itsjuncture with the arm is provided with a bearing edge 62 concentric to the pivot of the plate and terminating at one end in a recess 63 in the plate, the side of the recess remote from the bearing surface 62 being projected outwardly of said bearing surface to form a stop 64 to be later described. An arm 65 projects from the lever plate at its side adjacent the turn-table spindle and one end of this arm is upturned to form a cam 66 having an upper cam surface inclined downwardly in a direction away from the spindle. Intermediately pivoted on the base plate and extending between this cam and the spindle collar 19 is a lever 67 which has one end laterally directed for engagement by the cam to rock the lever upon counter-clockwise rotation of the lever plate 58. The other end portion of the lever 67 is relatively light, whereby the lever is normally rocked by gravity to raise said end portion, and this periphery o he collar. Thus, when the lever 67 is free to lift its end adjacent the collar and pawl lever, said end will engage the cam outer surface of the lever and will rock the lever against its spring tendency, to disengage the toothed end of the lever from the locking notch 21 of the turn-table position until the completion of the playing operation of the record, a holding lever 70 is intermediately pivoted on the base plate, and one end of this holding lever extends adjacent the bearing surface 62 and recess 63 of: the lever plate and is laterally bent to form a pawl engaging said bearing surface and recess, being resiliently ur edfor such engagement by a leaf spring 71 secured on the base plate 17, and bearing against its other end portion. This other end portion of the lever 70 is extended obliquely of the pawl end of the lever, and has its edge portion bent laterally upward to form an elongated bearing surface 72 which lies in a plane intersecting the tone-arm.

For rocking thelever 7 O to releasing position at the end of'a variable pro-determined playing interval, a slide bar 73 is mounted for sliding movement on the base plate 17 in a plane substantially parallelto the plane of the bearing face 72, said bar sliding in a bearing plate 74 secured on the base plate, and being incidentally parallel to the slide bar 54 which controls the variable outer limit :of movement of the tone-arm. The bar is frictionally held against sliding movement by a leaf spring 75 secured to the hearing plate 74; and engaging one edge of the bar. Pivoted on the end of the bar adjacent the bearing surface 72 of the lever 70 is an angular lever 76 having one end engageable against the bearing surface 72, and having its other end projecting outwardly of the periphery of the turntable for engagement by the pin 56 depending from the intermediate portion. of the tonearm. Thus, as the tone-arm reaches its desired inward limit of swinging movement, it will rock the lever 76 and consequently rock the lever 70 to retracting position, permitting swinging movement of the lever plate 58 undcrinfluence of its spring 69, to rock the lever 67 through the cam '66, and thus procure clutch engagement of the collar 19 with the turntable spindle 10 by releasing the lever 20. The lever 73 is set in accordance with the particular portion of the record at which the playing groove terminates, the playing grooves termlnating at dlfi'erent points for individual records, and thus settlng of the bar 73 may be procured by swinging the through the medium of the setting mecha nism for-an automatic stop disclosed in Patent No. 1302650 granted to me May 6, 1919.

To reset the, lever plate 58 in all operations of my'device, and to afford a positive stop for the mechanism and turn-table when the device is used as an automatic stop, an arm 7 7 projects inwardly from the lever plate 58, with its free end laterally directed and overlying the cam disk 25. Upstanding on the ram disk is an arcuate bearing rib 78 disposed in the maj or are of a circle having as its center the axis of rotation of the disk and adapted for engagement against its outer face of the arm 77 of the lever plate, the external diameter of this rib with respect to the lengths of the lever arm 77 and brake lever arm 59 being such-that upon engagement of the lever. arm 77 with the outer face of the rib upon partial movement of the lever plate 58 under influence of its spring,

the brake block 60 is held spaced from the turn-table wheel. At the portion of the rib diametrically opposite the space between its ends, there is formed a ram enlargement 79 which is gradually increased in width over the bearing surface of the rib, and which terminates in an abrupt shoulder, this cam enlargement serving .upon rotation of the disk to rock the arm'77 in resetting movement to reengage the pawl. end of the lever 70 in its notch63, and thus hold the lever plate set. Disposedbetween the ends of the bearing; rib 59 and offset inwardly of the bearing faces of said rib is a stop bar 80 carrying pins 8]. slidable in arcuate slots in the cam disk, whereby the stop bar is permitted longitudinal sliding movement between the ends of the disk, the bar being resiliently urged in aclockwise direction to its limit of sliding movement by a leaf spring 82 secured on the cam disk 25 and bearing against one end of the bar. A. stop projection 83 is formed on the bar at its end adjacent the spring, which is the rearward end or the bar with respect to the direction ofrotation' of the cam disk 25, and this projection extends substantially to the projected curved bearing surface of the bearing rib 78.- v

W hen. it is desired to utilize my device for repeating the playing operation of a record, the lever arm is not permitted to engage the stop projection 83 and to hold the lever arm from such engagement, an upstanding finger 84 is provided on the arm 59 of the lever plate 58. This finger is engageable by the hook end of a lateral arm 85 projecting from a lever 86 which has one end extending outwardly of the turn-table for engagement to rock the lever, and which has its other end movable between a pair of stops 8'? on the base plate 17, whereby the lever may be held in either of two positions, one of said positions engaging the linger 84 with the hook arm 85 of the lever, and thus limiting the rocking movement of the lever plate 58.

The initial or set position of the mechanism is identical for both the automatic stopping and the automatic, repeating operations after playing operation oi the record has been instituted, and in Fig. 1, the parts are shown in this set position, the ram projection 79 of the bearing rib 7 8 having just moved the lever plate 58 to retracted position, wherein the pawl end of the l vcr T0 is engaged in the locking notch 63 of the lever plate to hold the lever plate against movement under influenre of 'its spring 69. the collar 19 being disengaged from the turn-table spindle and the mechanisn being consequently idle.

In operation of the mechanism, assuming now that the control lever 86 is rocked to engage its hook arm 85 with the lever finger 84 and thus set the mechanism for repeating actuation, the previously set trip lever 76 is engaged by the tone-arm pin 56 at the completion of desired inward movement of the tone-arm, thus rocking the lever to releasing position, permitting rocking movement,

of the lever 58. This rocking movement of the l ver 58 will actuate the lever 67 by the cam 66 to release the clutch pawl 20 and procure drive connection between the collar 19 and the turn-table spindle. At the same time, the pin Set will move to engagement in the hook portion of the control lever arm 85-, and thus prevent further rocking movement of the lever plate 58, and this position of the lever plate when held by the pin 8i will be such that the arm 77 ot the lever plate will be moved inwardly so that lLS laterally turned bearing end surface will approximate the bearing surface 01 the rib 78. Driving rotation of the cam disk 25 being thus instituted, the pitman lin 7 will be shifted to actuate the sound box lifting and tone-arm swinging structure heretofore described to thus lift the sound box and swing the tone-arm outwardly to starting position, this starting position being determined by adjustment of the slide bar 54 in accordance with the size of record which is being played, as heretofore described. This shift ing and raising movement occurs during a half turn of the cam disk 25 which places the inwardly offset stop bar 80 opposite the free end of the lever arm 77, but the lever end is prevented from moving inwardly from the surface of the bearing rib 78 by abutment of the pin 84 with the hook arm 85. Rotation of the cam disk thus proceeds, and as the second half revolution is completed, the lever arm 77 is swung away from the cam disk by engagement with the cam portion 79, to thus re'e'ngage the pawl end of the'lever 70 in the recess 63 of the lever plate Playing rotation of the turntable continues during all this'time, and as the cam disk 25 moves through its second half revolution, the tone-arm and sound plate mechanisms move to set position and the sound box is gradually lowered onto the record to institute the repeated playing operation, and such repetition of the playing operation may obviously be continued indefinitely.-

When it is desired to automatically stop the phonograph upon completion of the playing operation of a record, the control lever 86 is swung to move its hook arm from the path of movement or" the lever finger 84. As the tone-arm moves inwardly to its desired limit of movement, its depending linger 56 engages the trip lever 76, rocking the lever 70 and releasing the lever plate 58 in the manner heretotoreset forth, and the clutch pawl lever 20 is released in the same manner, the free end of the lever arm 77 engaging the bearing face of the bearing rib 78, and in this instance being-held against further inward movement only by said hearing rib. Thus, as the end of the bearing rib moves past the lever arm, it is permitted to swing inwardly into the space between the ends of the bearing rib and thus to engage the friction block (30 of the lever plate with the depending wheelot the turn-table, thus instituting braking operation on theturntable,- and the stopping operation of the turn-table mechanism is further effected by engagement of the end of the lever arm 77 with the projection 83, thus bringing the mechanism to a positive stop. During this operation, the cam disk 25 has, upon a half revolution which has served to liit the sound box 16, swung the tone -arm and sound box back to starting position. Thus, at the completion oi": the automatic stopping operation, the sound box is held raised and the tonearm is held set, so that without necessitating manual manipulation of the tone-arm or sound box, the record may be removed from the turn-table and a new record placed thereon. To start the playingoperation, the lever 58 is swung manually in its'direction of resetting vmovement by grasping the finger piece 61. This swinging movement is limited by abutment of the pawl end of the lever 70 with the stop 64 of the lever plate 58, which is disposed at one side of its recess 63. In this relative position of parts, however, the lever 70 is prevented from moving into the locking recess 63 by engagement of its other end with a shoulder 88'formed intermediately on the pitman link 27 at the outer endyof a cut-away portion of said link. Thus when the manual gr1p on the finger 7 piece 61 is released, the lever plate 58-will lifting theneedle from the record swing under influence of its spring 69 to agaln move its arm 77 toward the cam disk rib 7 8 and to release the clutch pawl 20 by action of its cam 66 and thus start driving operation of the resetting mechanism. The

manual rocking movement of the lever plate 58 swings its arm 77 away from the projection 83, thus permitting the stop bar 80 to immediately'shift in a clockwise direction on the disk 25, under the influence of its spring 82. This shifting movement obviously prevents rengagement of the lever arm 77 with the projection 83, permitting the cam disk 25 to rotate, even should the lever arm 77 be immediately released, and the lever arm engages and rides upon the bearing surface of the rib 78, being gradually cammed outwardly so that in accordance with the previously described re-setting operation, the cam projection 79 serves to reengage the pawl end of the lever 70 in the locking recess 63, the shoulder 88 of the pitman link 27 in the meantime having moved to inactive position, this movement being incidental to operation of the resetting mechanism to effect its second half cycle of movement, lowering the sound boX 16 upon the record, and retracting the crank arm 33. 1

The lever 86 may obviously be shifted during any portion of the playing operation of the record to procure an automatic stop upon completion of the playing operation.

The structure aforedescribed is comparatively simple in nature, in view of its functions and thevarious adjustments permitted, and the device is positive in operation without setting up any violence of operative movements which might injure the record or needle, the slight turning pressure imparted to the spring operated tone-arm en- 1 gaging crank 33 being such as not to interfere with the playing operation when the crank is resiliently engaged with the tone arm, but yet suflicientto effect positive movement of the freely swinging tonearm upon groove.

In Fig; 8 a slightly modified structureis shown, for use in connection with that type of phonograph structure wherein a sound box is lifted from the record by upward However, it will be appreciated that various changes and modifications of structure may be employed to meet differing conditions of use, Without departing in any manner from the spirit of the invention, as interpreted by the appended claims.

It is noted that my operating mechanism .does not interfere with ordinary manual manipulation of the phonograph structure, also it will be noted that the apparatus may be caused to repeat at any time desired by exerting pressure on the lever 61 which will cam the lever 70 outwardly and incident to the repeating operation.
